It is related to the prefabricated building roof.

"Prior art" For detached prefabricated houses, for example, planned prefabricated houses called "freestyle" are supplied in place of the already standardized houses, and along with that, exterior and interior design A variety of variations have been developed to meet various needs, and in particular, the roof shape is an important factor in determining the style of the house. Various kinds of roofs, hipped roofs, square roofs, etc. are offered.

By the way, such a planned house can strongly aim for individuality of the house, but on the other hand, there is a drawback in that it has disadvantages in terms of construction period, cost, etc. due to increased dependence on site construction and increased types of parts. Yes, and above all, the roof
Unlike floors, walls, etc., whether using trusses, panels, or wire rods such as bundles or rafters, it takes a lot of time to construct a shed on site, especially on the roof of a dormitory. However, there is a problem that various types of parts must be prepared by considering various types of parts configurations corresponding to the roof shape.
